There is a kind of individualism so stark that it seems to dovetail with an existentialist creed: Manhattan is right at that crosshairs. You are pure potential in Manhattan, limitless, you are making yourself every day. When I am in England each summer, it’s the opposite: all I see are the limits of my life. The brain that puts a hairbrush in the fridge, the leg that radiates pain from the hip to the toe, the lovely children who eat all my time, the books unread and unwritten. . . .

I suppose it should follow that I am happier in pragmatic England than idealist Manhattan, but I can’t honestly say that this is so. You don’t come to live here unless the delusion of a reality shaped around your own desires isn’t a strong aspect of your personality. “A reality shaped around your own desires”—there is something sociopathic in that ambition.
